A driver has been caught at more than 120mph on the A47 with their two-year-old daughter in the car.
Officers from Norfolk and Suffolk Roads and Armed Police were conducting speed checks on the A47 at Terrington St John, near King's Lynn, on Saturday, September 14.
Within an hour police stopped three drivers travelling at around 100mph.
A supervised learner was stopped after going 94mph.
A driver was stopped after travelling at 126mph with their two-year-old daughter in their car and another was stopped for going 101mph.
Sergeant Chris Harris said: "Seriously it's unbelievable.
"Great work team and really disappointed to see drivers putting themselves, and others, in danger of being killed or seriously injured."
Drivers caught speeding at more than 100mph are referred to court, where magistrates can issue a driving ban, fine or six penalty points on a driver's licence.
